[OSM-dev] slippy map does not work in FireFox 3.0 for me

[Jens Scheidtmann]

Hi folks,

I have a problem with one of my computers:

When I open openstreemap.org, the map displayed only contains 
a gray ladder (zoom) at the left hand side, the scale at the bottom left 
and the Permalink at the bottom right on a white background. 

Even if I disable Adblock, Allow Javascript globally (Noscript) and disable
Greasemonkey, this is still the case. 

Running Firefox in Safemode does not help either.

Have you experienced a similiar situation somewhere?
If yes, how did you solve this?
Any hints, on what this could be?

Thanks in advance,

Jens Scheidtmann
